Cam Zink makes history with a 100-foot backflip

Cam Zink successfully landed a 100-foot, 3-inch dirt-to-dirt backflip on a mountain bike last night, setting a world-record live in front of a national TV audience.

Zink hit a top speed of 46 mph on a 910-foot runway, before flipping 100 feet and absolutely stomping the landing at Mammoth Mountain, California. By setting the new Guinness world-record, Zink surpassed his own unofficial record of 78 feet, which was set in Utah last year.
